Specification of Letters Patent.

Patented Feb. 11, 1908.

Application filed July 19, 1907- Serial No. 384.573.

To all whom it may concern:

Be it known that 1, Louis C. BEVIER, a citi-- zen of the United States, residing at Logan, in the county of Gallatin and State of Montana, have invented certain new and useful Im rovements in Adjustable Sights for Guns; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use same, reference being had to the accompanying drawings, and to the letters and figures of reference marked thereon, which form a part of this specification.

This invention relates to new and useful improvements in sights for guns, the object of the invention being to produce a simple and efficient device ofthis character which may be readily-adjusted for different ranges without the necessity of the person aiming the gun taking his eye off the game.

The invention comprises various other details ofconstruction and combinations and arrangements of parts which will be hereinafter fully described and then specifically defined in the appended claims.

I illustrate my invention in the accompanying drawings, in which Figure 1 is a perspective view showing the sight. raised. Fig. 2 is a vertical sectional view through the sight, showing the sight lowered. Fig. 3 is a detailed perspective view of the shank, showing the rack teeth thereon. Fig. 4 is a cross sectional view through the upper end of the sight, and Fig.5 is a detailed perspective view of the sight head with one of the slide plates removed.

Reference now being had to the details of the drawings by letter, A designates a plate which is preferably recessed as at A upon its upper surface, and B is a spring fixed at one end within said recess, the free endof the spring extending between the lugs D which rise from said plate.

E designates a sight holder having a diagonally disposed slot E formed therein, and D is a pivot pin which passes through apertures in said lugs and extend through said slot and upon which pin the said holder has a sliding pivotal connection. It will be noted that the free end of the spring bears yieldingly against the end of the sight holder when the latter is in a vertical position to retain the holder in such position and, when the sight holder is turned down, a longitudinal movement is imparted to the same in order to bring the pivot pin against one end of'the diagonally disposed slot and in which position the holder will be held in its lowered position and tension will be relieved upon said spring.

Mounted to have a longitudinal movement within said holder is a sight stem or shank H having rack teeth H thereon and a sight head K with an aperture K therein. The opposite faces of said sight head are recessed and N designates slides or plates, each having a minute peephole n therein. Said plates, it will be noted, are flush with the shank or stem H and are adjustably held by frictional contact with the undercut or dove-tailed edges of the slots. Said slots extend below the head of the sight so that, when the plates are slid down so as to expose the large aperture in the sight head, they will be located within the sight holder or jacket. One face of said sight holder is provided with a recess O which is intersected by said sight stem and mounted within said recess is a pinion wheel Q adapted to mesh with the teeth of said stem and said pinion wheel is fixed to a stub shaft J, one end of which is journaled in an aperture I formed in the wall of the sight holder or jacket,said stub shaft being held in its bearing by means of a nut J fitted to the threaded end thereof.

Also fixed to said stub shaft is a milled wheel nally disposed recess formed with one face of the sight holder or jacket and forms a resilient pawl, the free end of which is rounded and adapted to engage one or another of the grooves formed in the ratchet wheel L, which is fixed to and rotates with said shaft. It will be noted that the spaces intermediate the grooves or notches in the periphery of said ratchet wheel are rounded in order that said wheel may be turned in one direction or the-other under tension of said spring which serves as a dog.

Assuming a sight to be turned down in the position shown in Fig. 2 of the drawin s and it is desired to raise the holder, the. ho der is given a slight longitudinal movement, in order to bring the pivot pin to the opposite end of the slot, after which the spring bearing against the pivotal end of the holder will normally throw the sight holder to an upright position and will thus be held by the spring against being lowered accidentally. By turning the milled Wheel in one direction or the other, the peepsight may be raised or lowered, the partial rotary movement which is imparted to the milled wheel causing the resilient pawl to spring into one or another of the grooves or notches of the ratchet wheel with a click, indicating that the sight has been raised a certain distance, preferably for a one hundred yards range, and each click representing an additional one hundred yards in the range and this may be accomplished while the gun equipped with the sight is at the shoulder of the person using the gun. By this provision, it will be noted that the gunner may at all times have his eye upon the game or target and readily tell, by the clicking incident to the turning of the milled wheel, the range at which his sight is set. When it is desired to lower the sight, the holder is thrown back and given a slight longitudinal movement in order to bring the pivot pin at the opposite end of the diagonally disposed slot and in which position the spring will bear against the holder in such a manner as to hold the sight in its lowered position.

By the provision of a sight embodying the features of my invention and which may be fastened at any location, the spring which acts upon the holder will be free from tension both when the sight is in a raised or in a lowered position, as the spring is merely put under tension during the act of swinging the sight holder or jacket either to a vertical position or returning the same to its lowest position and, by the provision of the adjustable slides having peepholes, means is afforded for fine target shooting and, when the peepsight slides are removed, a large aperture for twilight or ordinary day shoot- My improved sight, which is simple in construction and neat in appearance, may be employed upon various makes of rifles with' or without long firing boltsi What I claim to be new is 1. A sight for a gun consisting of a recessed plate adapted to be fastened to the tang of a gun barrel, a sight acket having sliding pivotal connection with said plate, a spring bearing yieldingly against said jacket and designed to hold the latter either in a raised or lowered position, and an adjustable sight carried by said jacket, as set forth.

2. A sight for a gun consisting of a recessed plate adapted to be fastened to the tang of a gun barrel, a sight jacket having sliding pivotal connection with said plate, a

spring bearing yieldingly against said jacket and designed to hold the latter either in a raised or lowered position, a sight stem having rack teeth thereon mounted to have a longitudinal movement within said 'acket, a pinion wheel meshing with the teet of said stem, means for rotating the pinion and means for holding the stem in an adjusted position, as set forth.

3. A sight for a gun consisting of a recessed plate adapted to be fastened to the tang of a gun barrel, a sight jacket having sliding pivotal connection with said plate, a spring bearing yieldingly against said jacket and designed to hold the latter either in a raised or lowered position, a sight stem having rack teeth thereon mounted to have a longitudinal movement within said jacket, a pinion wheel meshing with the teeth of said stem, an operating wheel for turning said pinion, a ratchet wheel and pawl for holding said wheel and pinion in a fixed position, as set forth.
